Video-based task analysis: a tool for understanding your audience [radiology application]

Describes research efforts to adapt an ethnographic data collection technique called `stream-of-behavior chronicles´ to serve as a tool for task analysis in the design of the user interface of a radiology imaging system. In this version of the method, the authors capture the radiologists´ stream of behavior on videotape, they analyze it, and then show the tape to the radiologists to get a running commentary on it; this `stimulated recall´ procedure is also videotaped. This approach, combined with a small set of related approaches, has proved to be very powerful in helping the authors to understand their audience
